Subject: [PATCH] Fix tests for PyPy3.

On PyPy3 the following `registered_classes` for `IMutableMapping` are
found:

```
{<class 'dict'>,
 <class 'pkg_resources._vendor.pyparsing.ParseResults'>,
 <class 'setuptools._vendor.pyparsing.ParseResults'>,
 <class 'collections.UserDict'>}
```

So collecting the tests fails because of a duplicate name which is
prevented by this commit.
